Problems solved by technology

[0004] The above-mentioned prior art scheme has the following defects: 1. Use a large amount of spray liquid, which greatly wastes liquid resources
2. During the spraying process, the flue gas only passes through the spray liquid quickly without external force interference. The flue gas quickly passes through the spray liquid, which cannot filter out the particulate matter in the flue gas well.

Embodiment 1

[0055] refer to figure 1 , figure 1 It is a work flow diagram of a method for treating flue gas by utilizing waste water provided by the present invention, and the method includes the following steps:

[0056] Step S100, collecting wastewater, driving the wastewater through the driving unit and transporting the wastewater to the collection pool through the wastewater delivery pipe;

[0057] Specifically, the drive unit is arranged at the inlet of the waste water delivery pipe, and the drive unit is controlled to pump the waste water into the collection pool by turning on or off the electric control switch;

[0058] Step S200, the flue gas is conveyed and vibrated and filtered under the driving of the waste water, the position of the interface between the flue gas conveying pipe and the collection tank is lower than the position of the interface between the waste water conveying pipe and the collection pond, the waste water drives the flue gas conveying pipe to rotate and vibr...

Embodiment 2

[0067] see figure 2 , figure 2 It is another work flow diagram of a method for treating flue gas by utilizing waste water provided by the present invention, and the method also includes the following steps:

[0068] After the flue gas is conveyed and vibrated and filtered under the driving of the waste water, it also includes step S210, the waste water is adsorbed and filtered. By uniformly setting a plurality of through holes on the flue gas conveying pipe, the vibrated flue gas passes through the through holes on the flue gas conveying pipe. The particulate matter in the flue gas is further adsorbed and filtered by the wastewater.

[0069] Specifically, the vibrating device is set in the collection pool and below the outlet of the waste water delivery pipe. When the waste water comes out, it drives the vibrating device to rotate and absorbs the flue gas coming out of the through holes on the flue gas delivery pipe, wherein the through holes are evenly distributed in the f...

Embodiment 3

[0072] see image 3 , image 3 It is another work flow chart of the flue gas treatment method using waste water provided by the present invention. Before the waste water is adsorbed and filtered, it also includes the following steps: S220, electrostatic precipitating and filtering, and two polymer layers stacked on the flue gas delivery pipe , under the extrusion of the smoke, the friction generates positive and / or negative charges for the adsorption of small and medium particles in the smoke.

[0073] Specifically, a first polymer layer and a second polymer layer stacked with the first polymer layer are provided on the front part of the inner wall of the flue gas delivery pipe, and a third polymer layer and a third polymer layer are provided on the rear part of the exhaust pipe. The fourth polymer layer with molecular layers stacked; wherein, the first polymer layer and the second polymer layer are rubbed under the extrusion of the smoke to generate static charges, and the t...

Abstract

The invention relates to a method and a system for treating flue gas by using wastewater, and belongs to the field of flue gas pollution discharge treatment. The method comprises the following steps that wastewater is collected, and a driving unit drives the wastewater to be conveyed into a collecting pool from a wastewater conveying pipe; flue gas is conveyed and vibrated and filtered under the driving of the wastewater, the joint position of a flue gas conveying pipe and a collecting pool is lower than that of the wastewater conveying pipe and the collecting pool, and the wastewater drives the flue gas conveying pipe to rotate and vibrate and vibrate down large particles in the flue gas; the liquid level of the wastewater is detected, namely the liquid level of the wastewater in the collecting pool is detected through a liquid level sensor; and emptying and cleaning are performed, and the wastewater is discharged when the liquid level of the wastewater in the collecting pool is greater than or equal to a preset liquid level. The technical problems that traditional wastewater is directly discharged and is not used for driving a flue gas conveying pipe to rotate and vibrate to separate gases and harmful solid particles in flue gas, and the wastewater adsorbs the harmful solid particles in the flue gas and turns waste into wealth for flue gas pollution discharge treatment are solved.

Description

technical field [0001] The invention relates to the field of laboratory flue gas sewage treatment, in particular to a method and system for treating flue gas with waste water. Background technique [0002] With the advancement of social technology, there are more and more various laboratories for research and development of new products. The laboratory is the basic place for experiments. A large number of experiments in the laboratory will produce a lot of smoke, and if the smoke is directly discharged into the air, it will cause great pollution to the air and affect human health.
